Adverse reactions analysis of Aconiti Lateralis Radix Praeparata and mechanism prediction of cardiac toxicity by network pharmacology / 中国中药杂志

ABSTRACT

The aim of this paper was to provide reference for the clinical safety use of aconite through the retrieval of literature about adverse reactions,predict its mechanism of cardiac toxicity by using network pharmacology,and provide ideas for the studies on toxicity mechanism of toxic Chinese medicines. The papers on adverse reactions of aconite were searched to established a database and summarize the adverse reactions of aconite. The results of literature review showed that the main causes for adverse reactions in clinical use of aconite included overdose use,short cooking time,consumption of medicinal liquor/medicinal diet,external use and misuse and so on. Therefore,the dosage of aconite should be strictly followed in clinical application,and the decoction method should be notified to the patients in detail to avoid taking the medicinal liquor and diet containing aconite,so as to prevent the occurrence of adverse reactions as much as possible,and make the best use of aconite in clinical application in avoid its toxicity. At the same time,based on the results of literature review,the network construction and visual analysis of cardio toxicity produced by aconite were carried out by using the network pharmacology technologies. RESULTS: showed that aconite can be applied to eight biological processes such as action potential of cardiac myocytes,cardiac conduction-related cell signal transduction,cardiac myocytes contraction,action potential involved in cardiac myocytes contraction,and signal transduction from atrial myocardial cells to atrioventricular node cells,and three target genes(SCN5 A,GJA1,GJA5). It was predicted that Aconiti Lateralis Radix Praeparata may influence cardiomyocyte depolarization,intercellular information transmission and material exchange by acting on three target genes(SCN5 A,GJA1,GJA5) and regulating the sodium channel protein and the expression of gap junction protein,thus affecting the heart rhythm as well as its structure and function and causing cardiac toxicity.
